Binance is gradually migrating P2P and other wallets to Funding Wallets on the Binance App to enhance user experience. If you have a P2P, Pay, Card, or Gift Card Wallet, your funds will be migrated to your Funding Wallet, too.
The wallet balance shown on your Funding Wallet includes the total balance of crypto from your P2P buy/sell orders, Binance Pay, Binance Card, Binance Gift Card and Binance Pool.
